The thinness of the new atheism is evident in its approach to our civilization, which until recently was religious to its core. To regret religion is, in fact, to regret our civilization and its monuments, its achievements, and its legacy. And in my own view, the absence of religious faith, provided that such faith is not murderously intolerant, can have a deleterious effect upon human character and personality. If you empty the world of purpose, make it one of brute fact alone, you empty it (for many people, at any rate) of reasons for gratitude, and a sense of gratitude is necessary for both happiness and decency. For what can soon, and all too easily, replace gratitude is a sense of entitlement. Without gratitude, it is hard to appreciate, or be satisfied with, what you have: and life will become an existential shopping spree that no product satisfies.

A few years back, the National Gallery held an exhibition of Spanish still-life paintings. One of these paintings had a physical effect on the people who sauntered in, stopping them in their tracks; some even gasped. I have never seen an image have such an impact on people. The painting, by Juan Sánchez Cotán, now hangs in the San Diego Museum of Art. It showed four fruits and vegetables, two suspended by string, forming a parabola in a gray stone window.

Even if you did not know that Sánchez Cotán was a seventeenth-century Spanish priest, you could know that the painter was religious: for this picture is a visual testimony of gratitude for the beauty of those things that sustain us. Once you have seen it, and concentrated your attention on it, you will never take the existence of the humble cabbage—or of anything else—quite so much for granted, but will see its beauty and be thankful for it. The painting is a permanent call to contemplation of the meaning of human life, and as such it arrested people who ordinarily were not, I suspect, much given to quiet contemplation.
